Todd Walsh says the recent market rally may be misleading, and investors should be prepared for a "murky summer" ahead. Despite the S&P 500's (SPX) march towards all-time highs, Walsh expects a potential volatility event to hit the market. He believes that the Fed's cautious stance on interest rates and the potential for a "look-through" inflation narrative to take hold could be catalysts for a market correction. However, he remains optimistic about the longer-term outlook, pointing to growth themes like AI and innovation, which he believes will drive the market higher in the second half of the year.
